The limit equilibrium method (LEM) has been a main-stay of analysis for geotechnical engineers for decades. Applied typically in a 2-D plane strain condition the method has been extended in formulation to the method of columns in 3-D and is now gaining increased use in industry. The formulation of the 3-D method of columns has typically been presented in Cartesian coordinates and with the assum...

The Open System for Earthquake Engineering Simulation (OpenSees) is a software environment for the network-based simulation of structural and geotechnical systems. The software design of the structural and geotechnical models in OpenSees is modular and hierarchical to mirror the equations of structural mechanics. The mathematical software components for computational simulation are also modular...

Millions of financial losses and thousands of people which die are due to earthquakes that happen every now and then in all corners of the world. Safety against the hazards of earthquake relates to two basic factors: safety of the structure and site. Site's conditions play an important role in damages of structures. This factor has a geotechnical cause and could be appeared as seismic wave ampl...

Over the last four decades Geographical Information Systems (GIS) have emerged as the predominant medium for graphic representation of geospatial data, including geotechnical, geologic and hydrologic information routinely used by geotechnical and geoenvironmental engineers. GIS allow unlimited forms of spatial data to be co-mingled, weighted and sorted with any number of physical or environment...

A novel parallel hybrid particle swarm optimization algorithm named hmPSO is presented. The new algorithm combines particle swarm optimization with a local search method which aims to accelerate the rate of convergence. The hybrid global optimization algorithm adjusts its searching space through the local search results. Parallelization is based on the client-server model, which is ideal for as...

In an age of depleting earth due to global warming impacting badly on the ozone layer system, need employ technologies substitute those engineering practices which result in emissions contributing death our has arisen. One is one that can sufficiently replace overdependence laboratory activities where oxides carbon and other toxins are released. Also, it technology brings precision especially e...

Objectives of the Doctoral Program Structural, Seismic and Geotechnical Engineering SSGE consists of the disciplines and techniques that allow to understand, model and control the behavior of: (a) structural materials (concrete, steel, masonry, composites, bio-materials and materials for micro-systems), (b) structural systems (from constructions to bio-mechanical systems and micro-systems), (c)...
